This is a nice piece of modelling and cosplaying that really has show both the strong talents you both posses for this field of art. The collabl of all three together to create this theme and presented through your renditions of the characters has certainly paid off well and really makes it a believable piece of fiction. Your renditions of both characters is strong and your take on Shadow through the means of the coat, fur and short dyed hair work very well to making this portrayal alive than merely fiction. Your ideas have worked well and it certainly touches upon the elements of Shadow without going for anything too silly nor unrelated to the character, in a way, your cosplay is a strong portrayal of being close to a living version of Shadow. What's more this piece also shows the strong portrayal of story telling with how you protect Rouge and tell your emotions and thoughts through the expression and body language. It's an effective way of making this come to life as a complete photo and makes us eager to know more about what is going on.
Please keep it up since this really shows potentials.
